Battery Pack Operating Time

This appendix covers the following information concerning battery pack operating time:

● Increase battery pack operating time

● Conditioning a battery pack

● Disposal of a used battery pack

Increasing Battery Pack Operating Time

Battery pack operating time differs depending on several variables. To avoid unnecessary replacement, consider the following variables when determining how long a charged battery pack should last:

● Power management settings

● Hardware configuration

● Software applications

● Installed options

● Display brightness

● Hard drive usage

● Changes in operating temperature

● Type and number of installed PC Cards

NOTE:

The power consumption requirements for PC Cards vary widely. Some cards drain the battery pack very rapidly.

Battery pack operating time can be increased by as much as 50 percent by controlling the energy required by the computer and the energy stored in the battery pack.

Minimizing the Energy Required

To minimize the energy required by the computer, follow these steps:

● Set the power conservation levels in the Power Management

utility to Maximum.

● Customize the timeout value to work more efficiently with the

applications. The amount of battery life depends on the values selected.

Maximizing the Energy Stored

To maximize the energy stored in the battery pack, follow these guidelines:

● Condition the battery pack at least every 30 days to improve

overall battery performance.

● Keep a battery pack in the computer when using it with AC

power to supply the battery pack with a constant trickle charge.

● Store the battery pack in a cool, dry place when not in use.

Conditioning a Battery Pack

CAUTION: To avoid a loss of data, ensure that all data is saved before discharging a battery pack.

To condition a battery pack, complete the following steps:

1. Allow the battery to drain until the computer reaches hibernation and turns itself off. Do not plug in the AC adapter during this process. Also, the system should not be allowed to sleep. To prevent sleep, you may either use the computer while the battery is draining, or you may disable power management.

2. Plug in the AC adapter and allow the battery to charge until the LED light on the display stops blinking. Your battery gauge may read 100 percent for a period of time before LED light on the display stops blinking. Do not unplug the AC adapter until the arrow disappears.

Your battery is now re-conditioned, and you may begin using the computer normally.

The battery pack charge time may vary greatly from 2 hours to 5 hours or more, depending on many factors (including whether it is charged on-line or off-line).

Disposal of a Used Battery Pack

In the interest of safeguarding our environment. Compaq Computer Corporation recommends that nickel metal hydride (NiMH) and lithium ion (Li ion) battery packs be recycled. Battery packs should be handled in accordance with country, state, province, or local regulations.

CAUTION: Never attempt to open or service a battery pack. Opening a battery pack not only damages the pack and makes it unusable, but also expose potentially harmful battery components.

Power Management for Windows 98

The following power management features are available for conserving AC power and extending battery operating time:

● Power Management Settings

● Sleep

● Hibernation

● Battery operating time

● Rebooting After a Lockup

● Servicing Your Computer - Full Off Mode

Power Management Settings

Depending on your patterns of computer use, you can set different levels of power management. These different power management levels can be activated based on the amount of time passed since the last system activity. System activity examples include keyboard or mouse movement, CD or DVD playback (while under program control that monitors Sleep), and modem use.

Each of the following system components can be made to go to sleep after periods of inactivity:

● system (goes into Sleep (Standby) mode)

● screen (times out and goes blank)

● hard drive (spins down)

You can select different conditions or power schemes through Power Management.The optional settings are Home/Office Desk, Portable/ Laptop, and Always On. From the default settings, you can change the delay time settings. Note: the setting for hard drive must be less than or equal to the setting for System.

IMPORTANT:

If you're on a network, it's recommended that you set System Standby to Never.

There are five categories of power management settings under the Control Panel. The default setting for each feature is listed below in the tables.

Sleep

You can select Sleep mode instead of turning off the computer when you have finished using it. This allows the computer to wake up faster than turning it completely off and saves power over the active (On) mode. Compaq Presario Notebook computers have two levels of sleep, Hibernation and Sleep.

Hibernation - by pushing the power button once your computer will perform a save to disk followed by a shut down of the computer into Off mode.

Sleep - is a low power mode, also referred to as Standby mode. While in Sleep mode, your computer will maintain system information and open files. Unsaved information will be lost if you turn off your system prior to system wake-up, or if you lose power while using the AC adapter.

CAUTION: While in Sleep mode, your computer will maintain system information and open

files. Unsaved information will be lost if you turn off your system prior to system wakeup, or if you lose power while using the AC adapter.

Hibernation Mode

Hibernation helps conserve battery life and protects your data. Hibernation can be a routine power saving event, or can be the result of a low battery condition. As it enters Hibernation your computer will display a progress screen, as it automatically saves the machine state before it shuts down and turns itself off. Your computer will automatically go into Hibernation, when the battery has little power left, or when the system (operating on battery power) has been in Sleep mode for more than an hour. You can also manually initiate Hibernation by pressing the power button once while the system is active. To restore the computer's previous state, simply press the power button once again. While waking up, the computer will display a progress screen.

The following table shows the conditions and indicators for getting in and out of the various power management modes, Sleep, Hibernation, and Off.

Servicing Your Computer - Full Off Mode

If you need to install or replace components in your system, you must turn the computer off completely. Follow the instructions above for properly putting the computer into Off mode, unplug from the outlet, and remove the battery (see battery section for instruction on removing battery).

Rebooting After a Lockup

Occasionally you may encounter a frozen keyboard or a locked screen. To reboot your computer (as if from a cold start) press and hold down the Power Button for at least four seconds, which will cause a manual shutdown. Then, restart it with a single press of the Power Button. If it still doesn't recover, press the Power Button and hold it for four seconds to shut it down, then, remove the battery or unplug the AC power for at least 30 seconds. Reinsert the battery or reconnect AC power and press the Power Button once to reboot.

Battery Operating Time

Battery operating time is affected by variables, such as the following:

● Power conservation settings

● Hardware configuration

● Software applications

● Installed options

● Display brightness

Electrostatic Discharge

A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not be affected at all and will work perfectly throughout a normal cycle. Although, it may function normally for a while, then degrade in the internal layers, reducing its life expectancy.

Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions.

Generating Static

The table shows how different activities generate static electricity and at different electrostatic voltage levels.

Service Considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and reassembly of the computer.

Tool and Software Requirements

To service the computer, you need the following:

● Compaq screwdriver kit (Spare Part No. 161946-001)

● Torx T-9 screwdriver

● 3/16-inch and 5mm nut drivers (for screwlocks and standoffs)

● Small, standard screwdriver

● Small, Phillips screwdriver

● Diagnostics software

Screws

The screws used in the computer are not interchangeable. If an incorrect screw is used during the reassembly process, it can damage the unit. Compaq strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.

IMPORTANT:

As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage.

Cables and Connectors

Most cables used throughout the unit are ribbon cables. Cables must be handled with extreme care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.

Cables

Use the following precautions when handling cables to avoid damage to the cable or computer:

● Always handle cables by their connectors.

● Avoid bending, twisting, or pulling on the cables.

● Apply minimum required force when seating or unseating the cables from their

connectors.

● Place the cables in such a manner that they cannot be caught or snagged by parts

being removed or replaced.

● Handle flex cables with extreme care; they can tear easily.

CAUTION: When servicing these computers,

ensure that cables are placed in their proper location during the reassembly process. Improper cable placement can cause severe damage to the unit.
